SPECIFICATION forming part of Letters Patent No. 645,479, dated March 13, 1900. Applieationfiled December 17, 1897. Serial No. 662,346. (No model.)

To all whom it may concern:

Be it known that I, EDMUND I-I. LUNKEN, a citizen of the United States, residingat Denver, in the county of Arapahoe and State of of Colorado, have invented certain new and useful Improvements in Lubricators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to sight-feed lubricators; and it--has for its object a simplified and improved construction of the same whereby the cost of manufacture is cheapened, the efficiency of the lubricator increased, and the glass sight-tubes protected from danger of breakage.

The novelty of my invention will be hereinafter set forth and specifically pointed out in the claims.

In the accompanying drawings, Figure 1, Sheet 1, is a front elevation of a lubricator embodying my invention with the mirror and protecting-hood removed. Fig. 2, Sheet 1, is a side elevation of Fig. 1 looking to the right. Fig. 3, Sheet 1, is a sectional side elevation through the dotted line w a: of Fig. 1 looking to the right. Fig. 4, Sheet 2, is a sectional side elevation through the dotted line y y of Fig. 1 looking to the left, with the difference that the lubricator in this figure is provided with a condensing-chamber. Fig. 5, Sheet 2, is a side elevation of the lubricator looking to the left of Fig. 1 with the mirror and hood in section and with a slightly-modified form of condensing-chamber. Fig. 6, Sheet 2, is a sectional plan View through the dotted line 2 2 of Fig. 5. Fig. 7, Sheet 2, is a detail showing in side elevation the protecting-hood. Fig. 8, Sheet 2, is a detail sectional plan view through the glass tubes, mirror, and protecting-hood.

The same letters of reference are used to indicate identical parts in all the figures.

A represents the oil-reservoir,- preferably rounded at its back and with its front made fiat between two hollow projections a I), cast with the body of thereservoir, the former located at the top and the latter at the bottom thereof, as clearly shown in Figs. 1, 2, 3, and 4:. Between these boxes are arranged the glass tubes B and C, which stand side by side, the

former being the sight-feed glass and the latter a gage-glass forindicating the height of the oil in the reservoir. There is a threaded opening in the top of the box a directly over the glass C, made sufficiently large to permit said glass to be slipped down through it and through a threaded nipple c on the bottom of said box until its lower end rests on the shoulder in a threaded nipple 61 upon the top of the box b. Packed nuts 6, slipped over the glass, are then screwed upon the nipples c d to secure the glass securely in place, with its upper end resting in the nipple c, as clearly shown in Fig. 4. The opening in the top of the box a directly over the glass C is provided with a screw-plug f, and through said open ing thereservoir is filled with oil, the box Ct being provided at its side adjacent to the glass C with a chamber or channel g, communicating with the top of the reservoir, and the box I) being similarly provided with a chamber or channel h, communicating with the bottom of the reservoir. Directly beneath the glass C in the chamber h I have placed the drain-cock *6, though it might be placed anywhere else.

Referring now to Figs. 3 and 6, I will describe the connections of the sight-feed glass B. On the top of the box I) is an 'exteriorlythreaded nipple j, carrying the usual or any suitable oil-deliverin g nipplek, controlled by a valve Z and extending through the bottom of the box, as clearly shown in Fig. 3. A packed nut m, slipped over the lower end of the sight-feed glass, which is seated in the nipple j, is then screwed upon said nipple to securely hold the lower end of the glass. Upon lar at, carrying at its lower threaded end the packed nut 0 for securing the upper end of the sight-feed glass. The collar n at its upper end is interiorly threaded and is screwed upon a threaded nipple 19 upon the under side of the box a. The nipple p communicates with a channel q, cast in the reservoir, (see Fig. 6,) which extends to the back of the reservoir and communicates with the tallow or oil exit pipe D, leading to the steam-pipe. A valve 0, passed through the top of the box a or located at any point between the nipple p and the exit-pipe or even in the latter, controls the opening in the nipple p and, in conpermits a broken sight-feed glass to be taken out and a new one inserted in its place. A chamber 3 is formed in the box 5 just under I the nipple j and extends sufficiently far into the bottom of the reservoir to permit the oildelivery pipe E, which is inserted through an opening in the top of the reservoir, covered by a screw-plug F, to be screwed into an opening in said projection, as seen in Fig.

The water of condensation in Figs. 1, 2, and 3 enters the reservoir from a pipe G, connected to the steam-pipe and entering the top of the reservoir. It carries or communicates with a pipe H, extending down into the. reservoir nearly to its bottom and whose lower end is opened or closed by a valve 1, extending through the bottom of the reservoir.

The water of condensation, entering the bottom of the reservoir, floats the oil and by hydrostatic pressure forces it down the pipe E, chamber 3, and nipple 70, up through the sight-feed glass B, which is filled with water of condensation from channel q, and thence out through channel and pipe D to the parts to be lubricated. The gage-glass serves to show at all times the relative amount of water and oil in the reservoir, and when the oil is exhaustedthe water is drained therefrom and the cup refilled. In some instances the gageglass may be dispensed with and the lubricator may have only the sight-feed glass, in which case the reservoir would be filled through the plug F; or the gage glass might have substituted for it another sight-feed glass, in which case the chamber 9 at the top would not communicate with the oil-reservoir, but would,

communicate with the channel q, and the plug f would have substituted for it a valve similar to the-valve r, as will be readily understood. So in like manner any number of sightfeed glasses might be employed, either deliveringinto one exit-pipe D or by separate channels into separate delivery-pipes, to carry the oil to difierent-parts of the lubricator.

In Figs. 4 and 5 the reservoir is shown with a condensing-chamber J on its top, into which the steam is conducted from the steam-pipe to form the water of condensation. In Fig. 4 the valve I for admitting and cutting off the water of condensation is shown at the bottom of the reservoir, as in Figs. 1, 2, and 3; but in Fig. 5 the valve I is employed for this purpose and is located between thecondensing-chamber J and the top of the reservoir.

In Figs. 5, 7, and 8 I have shown a mirror K on the flat front face of the reservoir behind all of the glass tubes employed, whether one or more, to enable the attendant to morev readily ascertain that the oil is feeding properly or the height of the same in the reservoir by the reflection of said mirror. In addition,

however, to this mirror, which I call an indi cator, I prefer to surround the glass tubes with a perforated guard L of sheet metal or wire-gauze, in the front of which is secured a plate of glass M, extending the full width and depth of the glass tubes. Where the guard is used, I hinge it to one edge of the mirror-frame i, as seen in Fig. 8, and secure it to the reservoir by a pivoted hook it on the opposite side, so that when necessary the guard may be opened and thrown back to give access to the glass tubes.

By the above-described construction I provide a lubricator-reservoir having self-contained and cast therewith all the channels necessary for delivering the oil to the glass tubes and feeding it therefrom, and these are located in forward projections of the reser voir, between which the. glass tube or tubes are located, in such manner as to largely aid in protecting the same from accidental breakage, as will be apparent.

While I have illustrated the front face of the reservoir between the. boxes at b as being flat, which is my preferred form of construe-V tion, yet it is evident that this front face.

might be curved either inward or outward in a vertical plane, in which case the mirror would be correspondingly curved and also the fronts of the boxes a 79.

Having thus fully described my invention,

, I claim- 1. In a lubricator, an oilreservoirha ving at its front at top and bottom multiple fitting projections cast integral therewith, said 111-.

2. In a lubricat or, the combination of the glass-tuhe-su'pporting multiple fitting projections a and I) cast integral with said-lubricator and extending along the upper. and lower-parts of said flattened front, said lubricator being provided with the channels g, h, g and s, the oil supply pipe. E communicating with the said channel 8, the feed-water pipe H, and the sight'glass l3 and gage-glass 0 secured between the projectionsa and 6, sub

stantially as described.

3. In a lubricator, the combination of the reservoir A composed of an integral casting having a flattened front with integral multiple fitting projections CL and b at the top and bottom thereof, said lubricator being provided with the channels .g, h, g and 8 cast therein, the pipe E extending from the top of the reservoir and communicating with the said channel 5, thefeed-Water pipe H, and the sight-feed glassB and the gage-glass 0 secured between the said projections a and Z2, substantially as described,
